Characteristics of Sponges

The sponges are primarily in the Marine Biome, but about 100 to 150 species found in freshwater. They may look like plants but are actually animals that are sessile (unable to move). Often found attached to rocks, coral reefs, etc. You can find them in many different ways. Although some of them are straight pipes and a few others have fan-shaped body. Some are as crusts on rocks. You can also find sponges shaped cups, plants or shrubs and trees. There are sponges that have finger-like growths on them. Although colors vary with different types of sponges. There may be some white, beige, green shades of lavender, brown, yellow, red, purple, blue, etc. can have a width of about one inch taller than 1.5 meters. While some are cute, some are difficult. These can become brittle or so soft.

Almost everyone is familiar with the sponge trade, used for various purposes, such as domestic workers.  But there are some sponges live in salt water and fresh water at a time.  These sponges are living plants, but are regarded as animals that belong to the phylum Porifera.  The name of this phylum is derived from the pores of the sponge body and dies thus pores (in Greek).  This board is divided into three classes – Calcarea, and Demospongia Hexactinellida.  It is estimated that there are about 5,000 to 10,000 species of sponges and most of them are found in sea sponges are so unique aquatic animals, with interesting and surprising features.  Consider some of its features fluffy.

Thus, the sponges are primarily in the Marine Biome, but about 100 to 150 species found in freshwater.  They may look like plants but are actually animals that are sessile (unable to move).  Often found attached to rocks, coral reefs, etc. You can find them in many different ways.  Although some of them are straight pipes and a few others have fan-shaped body.  Some are as crusts on rocks.  You can also find sponges shaped cups, plants or shrubs and trees.  There are sponges that have finger-like growths on them.  Although colors vary with different types of sponges.  There may be some white, beige, green shades of lavender, brown, yellow, red, purple, blue, etc. can have a width of about one inch taller than 1.5 meters.  While some are cute, some are difficult.  These can become brittle or so soft.  Now that you know some basic properties of marine sponges, we have a detailed overview of various issues related to this animal.

* The body of sponges can be described as a variety of cell types.  In other words, the cells that make up the body of a sponge, not tissue, but is more or less ready to train the body.  Each cell type has a specific function.
* Even if one end of the body of a sponge is to be connected to the substrate (eg rocks), the other end an opening, called osculum.  In summary, the sponges are asymmetrical (sometimes displays a radial symmetry) hollow structures in the body wall.
* The wall of the body of a sponge is made of two thin layers separated by a thin gelatinous layer called mesohyl.  The exterior consists of cells in the epidermis.  This team has many pores that facilitate water travel within and outside the body.  Cells that are responsible for the formation of pores porocytes called.
* After the outer layer of epidermal cells and porocytes, the gel like inner layer called mesohyl it.  In this layer, there are certain cells called amebocyte responsible for the transport of nutrients, digestion of food etc. They are also responsible for the formation of spicules, which are considered the backbone of the fiber of this animal.  Plays an important role in sexual reproduction of sponges.
* The inner layer consists of cells that are whipped collar or choanocytes.  These cells use flagella to form a continuous flow of water in the sponge.  This helps to carry oxygen and nutrients to all parts of the body of the sponge.  They help to digest food and eliminate waste through osculum.
* One of sponge that is interesting is that the specialized cells of these animals have the ability to switch to other cell types.  Thus, sponges are specialized cells that do not have head, body, organ or appendage.  They are simple multicellular organisms.
* An important feature is that the sponges are filter feeders, they absorb nutrients and oxygen from water that enters the body through the pores.  Usually feed on bacteria and food particles in water, but some sponges are found to have a symbiotic relationship with microorganisms.  These microorganisms are capable of photosynthesis to produce more food and oxygen, which will be shared with sponges.  Some carnivorous sponges in the wild and feed on small aquatic animals such as crustaceans.
* Sponges can reproduce both sexually and asexually.  Although both male and female parts are in the same sponge, fertilization occurs only between sperm and eggs produced by different sponges.  Even if the sperm released by a sponge in the same organism enters the water poured into osculum.  Flight of the semen of waterways, including sponges and fertilize eggs in mesohyl.  After fertilization, the larvae find any hair a substrate for growth.
* In the case of asexual reproduction, the sponge may be exposed to regeneration where a broken part or a single cell can develop into a new sponge.  Another approach is by train, where the sponge will create new ones with a few cells on the outer surface of the sponge parents.  This new foam breaks off and grows as a new individual.  Other characteristics of sponges is the formation of a known outbreak gemmule in your body.  Gemmule this is hard and difficult, and if the pod is killed in adverse conditions, the plumule a new individual.

The above said is only a brief and general overview on the characteristics of sponges.  There are many more interesting facts sea sponge and surprising.  If you’re interested in learning more about these animals that can perform a thorough investigation on them.
